Exceptional Hardware and Software Meeting 2014 pushing frontiers of open source & DIY DESY Hamburg site, June 27-29 2014 http://ehsm.eu Abstract: The PCBWriter is a device to quickly produce high-quality printed circuit boards (PCBs). It uses a high power UV laser diode to directly expose the photoresist on the PCB. The direct exposure technique removes a lot of the typical problems with toner transfer or laser printer transparencies, allowing to reliably create PCBs even with the small...

Exceptional Hardware and Software Meeting 2014 pushing frontiers of open source & DIY DESY Hamburg site, June 27-29 2014 http://ehsm.eu Abstract: The mor1kx is a OpenRISC 1000 compliant softcore microprocessor written in Verilog. The initial motivation for the work at its inception was to provide a code base which would be friendly to multiple pipeline implementations, encouraging a high degree of reuse of common blocks. It initially saw the development of 3 different pipelines, each...

Exceptional Hardware and Software Meeting 2014 pushing frontiers of open source & DIY DESY Hamburg site, June 27-29 2014 Abstract: Electron beam welding is a technique for joining metals and alloys that was initially used in the manufacturing of nuclear fuel for atomic reactors around 1950. It has now used many other applications. The principle is to melt materials by heating them using a focused high energy electron beam (usually 6 to 120 keV). Traditional electron beam welders use a high...

Exceptional Hardware and Software Meeting 2014 pushing frontiers of open source & DIY DESY Hamburg site, June 27-29 2014 http://ehsm.eu Abstract: Quantum Mechanics is the framework for the laws of nature that are relevant when dealing with very small length- and energy-scales. As has widely been popularized, quantum mechanics leads to rather counterintuitive behavior when we consider small (and in special circumstances, sometimes even large) numbers of atoms. Thus far, most, if not arguably...

Exceptional Hardware and Software Meeting 2014 pushing frontiers of open source & DIY DESY Hamburg site, June 27-29 2014 Abstract: In 1994, the newly independent Latvia took over a formerly secret soviet military installation: The satellite tracking site at Ventspils, consisting of a 32 meter and a 16 meter dish. With its large telescopes in the middle of a huge, quiet, almost uninhabited stretch of forest along the Latvian coast, the Ventspils site is one of the most fascinating...

Exceptional Hardware and Software Meeting 2014 pushing frontiers of open source & DIY DESY Hamburg site, June 27-29 2014 http://ehsm.eu Abstract: The Cold War was a period of ambitious military, industrial and scientific projects, motivated by the competition with the opposing superpower. After the collapse of the Soviet Union, many of their facilities were simply abandoned, forgotten and left to rot.

Exceptional Hardware and Software Meeting 2014 pushing frontiers of open source & DIY DESY Hamburg site, June 27-29 2014 http://ehsm.eu Abstract: Justin Ginsberg will present a portion of his experimental artistic research with the glass working processes, which began in 2009. It was at this point that he recognized that glass, when very thin, was actually a flexible material. He will present the ways in which he constructs strands of glass, by hand, and with homemade machines, while also...

Exceptional Hardware and Software Meeting 2014 pushing frontiers of open source & DIY DESY Hamburg site, June 27-29 2014 http://ehsm.eu Abstract: As the Maker/DIY movement gets more technologically advanced, it encounters patent law. The speaker argues that the existing patent flexibilities, e.g. private, non-commercial or experimental use, are too narrow to be maker-protective. Designed to safeguard the freedom to operate, they do not fulfil their role in this specific context....
